In-Depth Analysis
With a base stat total of 630, Aggron plays as a slow bruiser that trades speed for raw hitting power. Its standout stat is Defense at 230, while Speed (50) is the clear soft spot — build sets that protect that weakness.
Defensively, the Steel combination gives Aggron 10 resistances, 1 immunity, and 3 weaknesses to plan around. Notably, it carries no 4× weaknesses, which makes it harder to punish. Offensively it pressures 3 types with super-effective STAB coverage.
A low catch rate of 45 makes Aggron a genuinely tough catch; bring strong balls and status moves. It levels on the Slow experience curve. Defeating it grants Defense +3 EVs, which is worth remembering when EV-training your own team.
